Running mocha test but Getting error: ReferenceError: document is not defined

Question

I am using mocha testing framework to test Http rest-api. I want to generate test-report for all test case, but when I ran mocha --reporter html > report.html
Getting following error

/usr/local/lib/node_modules/mocha/lib/reporters/html.js:263
  var div = document.createElement('div');
            ^

Answer 1

The reporter named html is only to be used when running Mocha in a browser. Running Mocha from the command line won't work with it.

There is a reporter named doc, which outputs "html documentation" according to mocha --reporters. By the way, when you run mocha --reporters you won't see html listed as a reporter, for the reason I've given above.

Answer 2

if you don't need to test it in a browser, then you can use jsdom-global:

mocha -r jsdom-global/register
